Windows XP Registry: A Complete Guide to Customizing and Optimizing Windows XP (Information Technologies Master Series)

Since Excel uses the rather generic name scheme of Sheet1 or Sheet2, you can more easily identify the type of data each worksheet contains if you give the worksheets more descriptive names. Names for sheets can be up to 31 characters long and are not case sensitive; however, a worksheet name cannot be left blank and cannot include a few special charactersnamely * / \ ? : [ ]

NOTE

Optionally, right-click on a worksheet tab and select Rename.
